Hurricane Helene leaves over 100 dead, millions without power in the Southeastern U.S. Here's what we know and what to expect next.

With many still unaccounted for, the devastation from Hurricane Helene continues to unfold by the hour.

The aftermath of Hurricane Helene is still unfolding across the Southeastern U.S., where more than 100 people have been reported dead, according to the Associated Press, and nearly 2 million were without power as of Monday afternoon.

The storm made landfall in Florida’s Big Bend region on Thursday night as a Category 4 hurricane with winds reaching 140 mph. Now downgraded to a post-tropical cyclone, Helene is still lingering over the Tennessee Valley, according to the National Hurricane Center.

In North Carolina, over 200 people have been rescued from floodwaters that washed away homes in several areas. Meanwhile, about 1,100 residents were staying in emergency shelters in North Carolina this weekend as the state deals with widespread damage.

Search teams are reportedly still trying to find roughly 600 missing people across several states, President Biden said during a news conference on Monday.

“We’re not leaving until the job is done," Biden said, noting that he's committed to traveling to impacted areas "later this week," having been told that a visit could potentially be "disruptive" to rescue efforts at the present time.

In response to the crisis, Biden further announced the approval of emergency declarations for the governors of Florida, North Carolina, South Carolina, Tennessee, Georgia, Virginia and Alabama. He also approved disaster declarations for North Carolina, Florida and South Carolina, allowing for federal funding to cover debris removal and provide direct financial assistance to affected residents.

"I will not rest until everyone is accounted for," he said.

Here’s a look at the destruction caused by Hurricane Helene — and what to expect in the days ahead.

As of Monday afternoon, more than 120 people have been killed across several states including Florida, Georgia, North Carolina, South Carolina and Virginia. According to the New York Times, the fatalities have reportedly been attributed to various causes, including flooding, falling trees and car accidents.

In Florida, where Helene initially made landfall, 13 people have been confirmed dead, per the New York Times. Florida Gov. Ron DeSantis described “complete obliteration” in parts of the state, with 90% of homes in communities like Keaton Beach on the west coast of Florida, still recovering from the aftermath of Hurricane Idalia in 2023, reportedly being washed away.

As of Monday, at least 25 people have been confirmed dead in South Carolina, prompting the state’s weather agency to call it “the worst event in our office’s history” in a Facebook post Saturday evening. Over 20 people, including children, died in Georgia as a result of Helene.

North Carolina has had 37 weather-related deaths as of Monday, according to the New York Times, and over 1,000 people were unaccounted for in Buncombe County on Sunday. Over 70 people remain unaccounted for in east Tennessee, officials said in a news briefing Sunday morning, per NBC News.

As of 1:40 p.m. ET on Monday, just under 2 million homes and businesses across Florida, Georgia, South Carolina, North Carolina and Virginia remain without power.

South Carolina was hit hardest, with over 720,000 residents still in the dark as of the latest update. Georgia follows with more than 560,000 customers without electricity, while North Carolina has just over 439,000 affected. In Florida, around 112,000 people remain without power, and over 94,000 are still impacted in Virginia.

AccuWeather estimates the total cost of Helene's damages and economic losses will be between $95 billion and $110 billion, positioning it as one of the costliest storms in U.S. history. For comparison, Hurricanes Katrina (2005) and Harvey (2017) each caused around $125 billion in damages, according to the National Hurricane Center.

Helene reportedly triggered the worst flooding North Carolina has seen in a century, with Yancey County hit hardest with 29.5 inches of rainfall.

Atlanta also saw record-breaking rainfall, with 11.12 inches falling over 48 hours, the most the city has endured since the 1800s. On Saturday, Georgia Gov. Brian Kemp said statewide damages may amount to more than the reported $1.2 billion the state incurred following Hurricane Michael in 2018.

In Florida alone, around 84 structures have reportedly been destroyed and over 4,000 have sustained water damage, according to Florida Urban Search and Rescue.

Over 800 FEMA staff are working around the clock to provide support and resources in the most affected areas, according to the agency. Evacuations have continued through the weekend as water overtopped several dams, including the Nolichucky Dam in Tennessee and the Lake Lure Dam in North Carolina.

As of Sunday morning, at least 190 people have been rescued in Florida, according to an update from DeSantis, and over 1,300 people are currently seeking refuge in 43 shelters across 21 counties in that state. More than 200 people have been rescued from flood waters in North Carolina.

Debris, downed trees and flooding led to more than 400 road closures in North Carolina, per the New York Times. Now, as of Sunday afternoon, there are at least 300 active road incidents, per the state’s Department of Transportation.

The Georgia Emergency Management Agency is reportedly in 32 counties across the state of Georgia, as they help local agencies in their rescue efforts.

The storm has been downgraded to a post-tropical cyclone and is now lingering over the Tennessee Valley, according to the National Hurricane Center. Parts of western North Carolina and eastern Tennessee — including Pigeon Forge and Gatlinburg — could see upward of 2 inches of rain through Monday.

While it's forecast to dissipate by Monday, the National Weather Service warns that heavy rain and flash flooding remain a threat for the Central Appalachians and Mid-Atlantic regions, with a slight risk of “excessive rainfall” expected through Tuesday morning.

Additionally, an upper-level low over the Ohio Valley is predicted to gradually weaken as it moves east toward the Mid-Atlantic by Tuesday.
